How can I use chezmoi add --exact without recursive behavior?

[thanhbinh01234]

After running chezmoi add --exact ~/.config/aria2, chezmoi adds all directories in ~/.config folder:

bash-5.3$ chezmoi managed

.config
.config/.DS_Store
.config/.android
.config/.keep
.config/.semgrep
.config/.wrangler
.config/1Password
.config/GitHub
.config/aria2
.config/aria2/aria2.conf
...

After that, I tried to clean the state by running rm -rf ~/.local/share/chezmoi/; chezmoi init; chezmoi add --recursive=false --exact ~/.config/aria2, it still adds all directories in .config.

So how can I add exact directories without creating .keep file in .config like in the warning in the doc?
Furthermore, after reading issue #4223, I'm still curious that why .config need to be exact (e.g the source path is ~/.local/share/chezmoi/exact_dot_config/exact_aria2/) instead of just aria2 (e.g. source path is ~/.local/share/chezmoi/dot_config/exact_aria2).

#4223 (comment) shows an experimental test I ran that shows why .config needs to be exact. If you have any file other than the exact_ directory in .config, it doesn't need to be exact_. This is why .keep is recommended.

Or start using chezmoi for more configuration than just .config/aria2.

Either way, the second note on chezmoi add was found because of issue 4223 and what was found with manual testing.

I'm not a fan of exact_, but I understand why it gets used.
